[imp] authentication problem in log files

[Todd Lyons]

Bernard Paris wanted us to know:

>I gest this is the same problem I posted on 16 oct 2001, "imapd Login 
>failure from IMP":
>Oct 15 14:48:52 guppy imapd[24717]: Login failure user=\200�)^H 
>Oct 15 14:48:55 guppy imapd[24715]: Login failure user=P')^H 

I had what seemed like the same problem.  It turns out that I was using a 
broken copy of imp.  I had copied over the horde directory from one of the 
developers I _thought_ it was a working, but he was neck deep into custom-
izing some stuff.  His changes had broken something so that it logged in 
twice extra with random characters.  I had been fighting this for some 
time.  I found it first with tcpdump, but thought I must have been reading 
it wrong.  Then when I ran the ldap directory in debug mode, it quite
clearly was doing a search for random characters.  The whole time it was 
acting like a dns timeout, so I concentrated on that.  The end result is 
that I got djbdns wired and running very smooth, but the timeout was
still occurring.  That was when I started looking back at the imap server 
and found the extra logins.

I was fortunate in that I had a properly working copy of imp to use for
comparison.
